EXPANDING HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 322,671, dated July 21,1885.

Application filed July 18, 1884. (No model.)

To all whom it may concern:

Be it known that I, CHARLES C. ALLEN, of Salinas city, county ofMonterey, and State of California, have invented an Improvement inExpanding Horseshoes and I hereby declare V the following to be a full,clear, and-exact description thereof.

My invention relates to that class of horseshoes jointed at the toe andadapted to expand, whereby contraction of the hoof is prevented.

My invention consists in a two-part shoe, jointed together at the toe bya plate or strip on the upper side and a toe-calk on the low r side,both plate and calk being pivoted to each part of the shoe, as I shalldescribe.

The object of my invention is to provide an expanding shoe having adouble joint at the toe, formed below with the toe-calk and above with aplate, which strengthens the joint and prevents sand from working inunder the hoof.

Referring to the accompanying drawings,

Figures 1 and 2 are perspective views of my plate into each part of theshoe, and the heads of the bolts are countersunk.

The object of the plate B is to prevent sand from working up under thehoof, and also to strengthen the joint which the parts of the shoe formwith the toe-calk D. This toe-calk lies under the shoe, and is pivotedto each part thereof by bolts E.

I am aware that it is not new to pivot the parts of a shoe to a plate onthe upper surface, nor to a toe-calk on the under surface; but I am notaware that both plate and calk have ever been used in the same shoe, andtherefore confine myself to the presence of both, as enabling me to makea strong and durable joint.

CHARLES C. ALLEN.
